Prices are per country and per month, VAT included: Start and Pro each cover one country, so two countries means two subscriptions — or Enterprise. You subscribe through the country portal you choose above, from Start; the key is created automatically once the payment clears and arrives by email. No plan changes by itself. Free is for looking around — it carries no API key.
More than one country, the cross-border comparison routes, and a monthly delivery into your own database. Priced per engagement, so it starts with a conversation rather than a checkout.
